dear team

there is a question about DS125DF111.

in the datasheet, it is only mentioned that we can support PRBS generator, but not mentioned PRBS check. so want to double check with you. do we support PRBS check function?

what data rate do our PRBS support? I can just find the 12.5Gbps, 9.8304G，10.3125Gbps. how to calculate or just a fixed value?

Best and regards

Zhang Chi

    Hi Zhang,

    The DS125DF111 and DS110DF111 do not support the PRBS checking function.

    As shown in the datasheet, the output datarate is approximate and free-running.  This means the actual output frequency will wander enough to make a PRBS check at any specific frequency unable to work consistently.

    Regards,
